Research Interests
My research focuses on structure-based protein engineering. We explore the structural and biophysical basis of protein interactions, including receptor-drug, protein-protein, protein-toxin, protein-pathogen, protein-nucleic acid and protein-small molecule interactions. We apply structural elements found in natural proteins (molecular biomimetics) to engineer novel fusion proteins (protein nanotechnology) for a wide range of purposes. For example, my team and I have designed and produced fusion proteins containing intrinsically stable helical spacers to (1) introduce large cavities into crystal lattices (for the study of protein dynamics by crystallography); (2) develop self-assembling oligomeric protein scaffolds that display on their surface multiple copies of an epitope of choice at specific angles and distances (for the design of novel vaccines, structural vaccinology); and (3) produce rigid G-protein-coupled receptor (GPCR) fusion proteins that aid structure elucidation by cryo-EM of receptor-drug complexes. We furthermore explore novel fusion proteins as tools for in situ structural biology, both at near-atomic resolution and at the mesoscale (fluorescent sensors for the detection of important mesoscale cellular rearrangements involved in cancer metastasis; probes for the detection of toxin- or pathogen- receptors on cells; novel fusion proteins for the detection of proteins in large complexes in cryo-EM tomography).
